Unresolved threads UI is moving when navigating to next unresolved thread

Using macbook m1 pro(14 inch) and brave browser, when i navigate in a MR which contains threads, and i click next unresolved thread(down arrow), the ui moves, and my cursor is on the assignees section and specifically on the None - Assign yourself button. So when i try to move multiple threads ‘down’, after the first click, the second one is on a different section, making my click doing a totally different thing. This issue is not in-place from the second-clicks onwards, as the down arrow UI does not move anymore
